Hello,

I see the {..} syntax in haskell code and at this point I don't understand what it means.. Any hint? The best would maybe be a link to the relevant "real world haskell" or "learn you a haskell" pages, if they exist.

Unfortunately as soon as you have such special characters, google is pretty useless...

Thanks!

Emmanuel
